From my observation of the "c:
windows
temp
" directory
a temp file is created but not the one that Trac is looking for
I don't know enought Python but it must be related to a "makeTempFile" command not returning the correct temporary file name.

after resolving the DLL conflict
using tracd Enscript perfectly render the syntax highlighting
using Apache v2.0.55 under Windows 2003 now the error log is not quite the same

I tried all these combinaison:

I set

and also tested by completely removing the line
and Trac still log that error:

I asked on the mailing list to be sure, someone told me "Trac is always set to prefer SilverCity over Enscript."
I do have installed SilverCity v0.9.5 (for Python v2.3)
so I think there is 2 problems now:
- why Trac do not use SilverCity over Enscript ?
- why Enscript working with tracd but not with Trac cgi under Apache ?

Replying to eric:
Also getting this on a centos 4.2 box
Check if SELinux is active, and if so look for AVC denial messages.
comment:7 by , 18 years ago
(was Dup: #4424) I have a very similar issiue, enscript cannot be started when I use mod_python, also other external pograms cannot be launched e.g. htmldoc for PageToPdf.
NO I don't habe SELinux installed!
Trac 0.10, with Apache 2.2 (problems only with mod_python!, running that thing in fcgi is perfect.)

| Component: | browser → mod_python frontend |
|---|---|
| Milestone: | → 1.0 |
Brief summary:
- this issue was originally reported for Enscript on Windows with Apache cgi,
while it was working with tracd
... np = NaivePopen(cmdline, content) File "C:\Python23\Lib\site-packages\trac\util.py", line 282, in __init__ outfd = file(outfile, 'r') IOError: [Errno 2] No such file or directory: 'c:\\windows\\temp\\tmpqdmftd'that particular error was "fixed" after correcting some dlls (see #2233) - then it was reported also on Linux, for PHP:
... np = NaivePopen(cmdline, content, capturestderr=1) File "/usr/lib/python2.3/site-packages/trac/util/__init__.py", line 146, in __init__ errfd = file(errfile,'r') IOError: [Errno 2] No such file or directory: '/tmp/tmpRiIHb2' - and in #4424 for enscript (when run from mod_python)
... np = NaivePopen(cmdline, content.encode('utf-8'), capturestderr=1) File "/var/lib/python-support/python2.4/trac/util/__init__.py", line 142, in _ _init__ outfd = file(outfile, 'r') IOError: [Errno 2] No such file or directory: '/tmp/tmpuzLyax'
… so I wonder if the trouble we see here with NaivePopen and mktemp from within Apache couldn't be due to some other implementation of mktemp suddenly becoming active due to a mix of libraries?
In any case, this does seem to be a valid issue, but with no immediate resolution plans, therefore setting it to milestone:1.0.
If those seeing the issue could get the list of libraries for their running apache process (see TracTroubleshooting for details) and look for mktemp / mkstemp symbols there, I'd be interested (nm $lib | grep mktemp).

Not likely to be resolved on our side.
comment:10 by , 12 years ago
I had exactly the same errors as described here and the solution which fixes the problem is: Copy states.exe, libiconv-2.dll and libintl-2.dll to a directory that is part of the PATH environment variable of Windows. Then it can be found by enscript.exe and everything works well.
It seems to me that, in enscript.py of Trac,
NaivePopen(cmdline, content.encode('utf-8'), capturestderr=1)
which calls
enscript.exe --color -h -q --language=html -p - -E%s
is not able to reuse the environment of enscript.exe, because actually both DLLs and states.exe is located in the same dir as enscript.exe.

Well, to speak more clearly, my workaround refers to [commment:2] of zwetan who said
Exception: Running (C:\buRRRn\shell\enscript\bin\enscript.exe --color -h -q --language=html -p - -Ejavascript) failed: 0, 'states' is not recognized as an internal or external command, operable program or batch file.

Yes, this seems to be a duplicate of #811.
